Hi all,
i own a p9 lite that was on Nougat VNS-L31C432B381 and i decided to rollback to MM. Following Huawei website instructions I downloaded two packages (rollback package and MM) and with 3 buttons method I flash first the rollback package and then MM. All went right and the ROM was stable. After a while of testing (that's why i went to MM), I decided to upgrade to nougat again. From updater it download and install the new android version (1.25 GB). After reboot I noticed that some system app was missing (file manager first). At every reset/factory reset some system app disappear. I repeated the procedure to rollback and upgrade again with the same result. The only way to use the device was to reflash MM and don't upgrade. Here some information I found:
- my starting version was Nougat VNS-L31C432B381
- now I'm on VNS-L31C432B160 (B160 isn't for dual sim? i have the single sim version) stock recovery bootloader locked
- updater try to install VNS-L31C432B370 (instead of B371?)
- if I try upgrade throught updater SN became something like ndr90 test key
- I tried to restore data,syste,vendor,oeminfo ecc.. from backups made with TWRP in Nougat (maybe wahile i was on MM, I'm not sure). It show the correct SN but ROM was still unstable
- I thought to try install full Nougat ROM but i didn't find any package
Can someone help me?
Thank you
The B37x update that the phone automatically finds after rollback doesn't work and will take you to ndr90 test key as you found out B160 is dualsim so you should flash the 161 one. Then use this guide to update through firmwarefinder/proxy https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-b388-nougat-maybe-b381-guide-t3612072
If you want to unlock your bootloader you can also flash B3xx through twrp. If not, the guide above works fine.

Hi Mara-X and thank you for you answer.
After I write the post i found the B161 package and i decided to give it a try. After flash (all ok) I launched updater again and it download the B371. The update went well and now i'm updating at B381 again throught updater. I think, when it was done, i'll factory reset the device for a clean install. So it seems the problem was B160/161 -single/dual version.
SOLVED: please check my 2nd post.
Hello guys,
I would like to upgrade my P9 Lite L31 from M to N official. I've tried the past few days but it always ends up with "NRD90M test-keys" on build number and missing apps. I have read A LOT of threads/posts about this issue, really everywhere, but I can't figure out how to update my device without problem.
Also I do know there are some Q&A threads/GUIDES/HOW-TOs in the forum but I don't find the right procedure for my case.
I assume it's because I've flashed the wrong package or forgot something in the procedure...
I've followed this GUIDE by @simo255: https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932
Here is my info:
P9 Lite VNS-L31
3 Gb RAM
Build: VNS-L31C900B151
EMUI 4.1.1
So, I'm on C900B151 and I'd like now to upgrade to C432B380 (or C432B381 ?) (or above if available).
If I understand well, the correct procedure is:
1- unroot (necessary?)
2- change from C900 to C432, by flashing an C432 OEMINFO.img through Meticulus TWRP (v4)
3- flash the latest Nougat update.zip package (B370/B371 or B380/B381) through Meticulus TWRP (v4)
4- flash the latest data full EU zip (B370/B371 or B380/B381)
5- reboot
Is it OK?
At steps 3 and 4, do I have to get UPDATE.app for B3xx and use the dload method instead?
FYI, I didn't follow step 2 when I tried, is it the culprit of my CUST errors in TWRP/"NRD90M test-keys"/missing apps problems? Or is it because I've flashed B370 instead of B371?
A few questions:
1- Is it a problem to currently run B151 firmware for my L31 for the Nougat upgrade process? I've read that the last digit means dual SIM or single SIM. I think I have a single SIM version but I'm not sure... How to know for sure? Sorry for the dumb question
2- If I don't follow the procedure above but if I relock my BL and then check for updates, do you think I will get a Nougat full OTA for C900 (C900B151 > C900B3xx)? Is it really necessary for me to change from C900 to C432?
3- In any cases, would it be possible to upgrade directly from B151 to B38x? Or do I have to go through B16x or B37x?
4- I can't figure out how to get the correct full OTA for Nougat, the one bigger than 1,9 Gb. I always get 1,25 Gb package through OTA update in settings, even when I'm running C432B160...
5- Is it possible to use Firmware Finder to update from B151 directly to B38x (or above)?
I already tried to flash a B370 update.zip and data full EU (from this GUIDE) but I have error about CUST in TWRP and as already said, then I get "NRD90M test-keys" on build number and missing apps after reboot.
After this, I successfully downgraded to C432B160 (maybe it would be better to downgrade to B161?) and I get the B370 OTA (1,25 Gb), but as you know it's not the FULL OTA... So AGAIN: "NRD90M test-keys" on build number and missing apps.
Sorry for the long post but I find really hard to flash/update stuff on this P9 Lite. I'm really confused. I was before on a Samsung S3 LTE and it was easier...
Any advices?
Thanks in advance.
I solved my problem!
My mistake was to install build VNS-L31C432B160 instead of VNS-L31C432B161, that's why OTA available was not the correct one (1,25 Gb instead of 1,99 Gb)
B160, B370, B380 are for dual SIM
B161, B371, B381 are for single SIM
I have a P9 Lite L31 SINGLE SIM
I was on previously on build VNS-L31C900B151 and I'm now running build VNS-L31C432B381 official and everything is working well.
The steps:
1- Download Update.zip of VNS-L31C432B161 (size around 1.6+ GB) (I've found it and downloaded it with Firmware Finder)
2- Extract the UPDATE.APP of the ZIP with 7-zip or similar and copy it on External SDCARD in a dload folder
2- Make sure to be rooted (Bootloader unlocked, TWRP v4 by Meticulus installed and SuperSU flashed)
3- Flash OEMinfo.img and custom.bin for C432 Single SIM (download link: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873, from this thread: https://drive.google.com/drive/folders/0B3CRCPqinridRXNPdDNuM2g5dTA) with Toolkit (download link: https://forum.xda-developers.com/devdb/project/?id=16538#downloads from this thread: https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873)
4- Reboot > It asks for decryption key (I entered a wrong one because I didn't even know the code) > it fails to decrypt and then ask for factory reset
5- Factory reset fails (I don't know why)
6- Reboot on Android > build is now VNS-L31C432B151 (it changed from C900 to C432 thanks to the OEMinfo.img and custom.bin)
7- Shutdown the phone
8- Start the phone with 3 buttons method: vol- ; vol+ ; power
9- Wait a few minutes L31C432B161 to be installed > It reboots and you're now running L31C432B161
10- Search for OTA in ROM settings > You will get L31C432B371 > Download and apply the update
11- Wait a few minutes L31C432B371 to be installed > It reboots and you're now running L31C432B371
12- Search for OTA in ROM settings > You will get L31C432B381 > Download and apply the update
13- Wait a few minutes L31C432B381 to be installed > It reboots and you're now running L31C432B381
14- Done!
So i have the same problem.
I've the L21 Dual sim model (2GB) and i tried to update.
Messed up with firmware finder and ended up with a wrong update. I've managed to get back to L21C432B160.
What version do I pick with Firmware finder? Or do i need to flash another OEMinfo.img en custom.bin first to get an update?
I don't want to end up with beta firmware or something messed up so I keep getting future updates. I don't understand why the OTA update is still here on my p9.

Which oeminfo.img and custom.bin did you flash lately? Is it your own files or from someone else?
And you say you are currently running L21C432B160 but which OTA version is showing up now in ROM settings? Which size?
Sent from my P9 lite using XDA Labs
Haven’t flash any of these files yet. I dont have an ota in upater right now. That is The probleem. Only with the firmware Finder i can get updates but i dont know which i should pick

If you want to get OTA updates, you need to have your bootloader locked. Is your bootloader currently unlocked?

Yes. But the problem also occured when it was locked.

I meant once you run full working Android 6, you have to go in Android settings, in a menu called something like "system updates" or similar and you should see if a newer Android version is available, meaning Android 7.
I'm running Android 7.0, so I can't show you screenshots from Android 6,sorry... Here are 2 screenshots from EMUI 5.0 (Android 7) in case it could help.
[SOLVED] Hi i was on l-31c432b381 firmware with emui 5.0 and android 7.0, i have unlocked the bootloader for install magisk 12.0 and have root permissions, after months i saw an update for my phone (b389) so i tried to upgrade but i had twrp so error 1 or 7, i flashed the stock recovery, redowload the update and the install failed at 5%, so i tried to unistall magisk before update, but nothing it wont update, after few tries the upgrader says that the update now is not 300mb but is full and is 2gigs, so i think is the time.. but no. so i tried to force the update with 3 buttons recovery dload method but it doesn't work at all 5% at every try. so i searched for support and i found that the ota connot be installed on unlocked devices, so i tried to relock my bootloader with oem relock and the unlock number but it says root type is risk... so i can't even relock my bootloader.. other says that i have to install to relock or can relock... but is b381 the stock? or they instend the mm version? i don't remember what version p9 lite ships. i tried to flash imgs through fastboot but even if i flash system and boot of the b389 the system boot and the info are of the b381, unisatlling app system crash, so i restored my previous backup made through twrp recovery, i immidiatly noticed that the huawei boot animations was gone and was an android stock animation. i thinked it was fine and all was working properly, i give up o upgrade and i was fine but sad. after few hours i tried to make a paper copy with my printer that have nfc but my phone keep shows and hide nfc symbol like on off on off on off over and over even after reboot, after a call i understand that the audio doesn't was working, every type of audio not work even the mic. i don't see any other problems but without sounds is unusable as a phone or mulimedia things... sorry for bad english please HELP i tried all i founded ...

Hi, my english is bad too , B389 is an OTA update, its impossible upgrade via fstboot or via TWRP (error 7). IMO the right way to fix your problems - downgrade to MM , then back to Nougat etc. (remove pattern Lock , Fingerprint lock, root etc. before installing downgrade). It will erase all your phone data!!!
Download official rollback package for your VNS-L31C432
http://download-c1.huawei.com/download/downloadCenter?downloadId=93789&version=373429&siteCode=sk
and download MM firmware VNS-L31C432B161 (Single SIM)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66022/f1/full/update.zip
1) Create a new folder dload in root directory of SD card (root directory : it means dont put it in any folder .) Now unpack the rollback package and copy its contents “UPDATE.APP” to the “dload” folder. Use the 3 button combo installation. After your firmware version should now be on “B300” or "test-keys".
2) Remove from dload folder rollback package, extract the ZIP file with MM firmware to the dload folder and use 3 combo button installation.
Or you can use this method : on your phone launch the phone dialer app and dial *#*#2846579#*#*. Next, select Project Menu – > Software upgrade – > SDcard upgrade – > and confirm the flashing process that is about to be initiated.
Good luck!

Yes, you can. Via OTA, or you can use TWRP (Meticulus 3.0.2.0 only ! ) and flash both .zip files. You must download two files:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v80474/f1/full/update.zip
and
http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_VNS-L11_hw_eu.zip.
In TWRP set Install, then select memmory SD card, and klick on
update.zip, confirm installation. After, STAY in TWRP, go back to Install, find file ...hw_eu....zip , confirm installation. Then select rebot system. Done!

Try it, but I think, you will get a message "not compatible" . Via dload its impossible, IMO use rather Huawei firmware finder or wait for OTA update.

FF works with proxy fine, but you must first download and install Firmware finder proxy apk. On Nougat use TWRP 3.1.0-2.

FF works with proxy , but you must download and install Firmware finder proxy apk. On Nougat use TWRP 3.1.0-2.
OMG, sorry !
Hello,
Recently a Huawei P9 lite VNS-L21 came into my hands. I experimented a bit with unofficial ROMs but eventually flashed the official back. I had flashed an earlier version, ending in 380 I believe, but because the phone attempted to upgrade to the next incremental update (say, -382) I decided to upgrade myself to the latest supported version (506). I used Firmware Finder to find the firmware and downloaded it to SD card.
Upgrade succeeded - since I had left TWRP recovery in the phone, I used the HuRUpdater which worked flawlessly.
The only small issue is that following this update, a red message is displayed on boot saying the device has failed verification.
Any way to solve this?

Hello,
my doubt is that you flashed a different firmware version from the one you had, thus corrupting the device's oem file. Could you post which was the latest complete firmware without this problem and the last one you downloaded and flashed? ( ex. L21CxxxB382 & LxxCxxxB506 ).
Let me know this info ...
Hi,
I went from l21c432b380 to l21c432b506 during this process. Stock OEM file was flashed before the -380 upgrade (no errors existed, the 380 upgrade followed a flash of -370).
I'm not sure why this is happening - I mean, both firmwares were from the firmware finder app... Weird, to say the least.

Yep, you used correct file but anyhow the firmware has been corrupted.
I think you have some ways to solve...
1 - if you have stock recovery, reboot into it and
download and flash the same latest firmware.
If you do not have it, you can extract (with huawei update extractor) it
(should be recovery1.img) from B506 firmware (update.zip) you already got,
then can be flashed via fastboot commands.
2 - Flash a previous or B380 firmware via HuRUpdater, then
update to latest via Firmware Finder with dns/vpn method.
3 - Repeat the whole job you done with B506 firmware. (via HuRupdater)
4 - Reboot recovery, reflash L21OEMinfo file, dual sim one, then the latest firmware again...
P.S.: method 1, 2, 4 will re-lock the bootloader, no problem if still you got the code...
Beware method 4, after you flash the oeminfo file do not shout down, reboot to bootloader
and unlock it again with the code. Device will reboot into twrp, then flash B506 firmware.
Good luck and let the community know..

For dual SIM only!
1. Unlock bootloader , (get unlock code here )
2. Install TWRP 3.0.2.0 (the p9 lite section is full of instructions on how to do it)
3. Download VNS-L31C432B370 fullOTA-MF-PV firmware (2 ZIP files), link:
https://cloud.mail.ru/public/D4kV/xcpuDX7Eu/
and copy downloaded files to the SD Card
4.reboot to TWRP, tap Install, Select storage Micro SDCard
5.Flash update с432b370.zip
6. go back without reboot (!!!), flash the additionnal package update_data_full_VNS-L31_hw_eu.zip
7. In TWRP's main menu select Reboot system.
Note: read the instructions carefully, check unfamiliar terminology by google or xda.
After successfully installing EMUI 5, you can upgrade to a higher build number via the dload method and Service ROM
B416
(Instructions can be found in ReleaseDoc folder).
Good luck!
P.S.:keep in mind that all firmwares that end with even numbers are for dual SIM (odd numbers are for single SIM).
